Method

Can selected either the ACI General Method or the PCI Design Handbook method.

Shear Force Considered

For the ACI method only.
Shear force to be used in the computation of the horizontal shear stress. Total loading uses Vu when computing the horizontal shear force. Composite loading only uses all loads on the composite section.

Horizontal Shear Stress

For the ACI method only.

This option controls which method should be used for determining the horizontal shear stress. VQ/Ib is typically considered an elastic response where V/bd can be used for both elastic and elastic responses.

Use effective mu for shear friction

The effective coefficient of friction from the PCI Design Handbook will be used if checked. This is only valid, per PCI, if no load reversal is present.

Compression Steel

Additional steel in the slab. This steel is assumed to be yielding in compression and produces additional compression stress in the top slab.
